There is an Instagram account too. But naturally, the Met, as the police force is known, doesn’t put pilots in the sky just to take nice pictures. The police helicopters’ main jobs include helping find suspects, ferrying police dogs around, pursuing vehicles, and more. Jobs they take seriously, with the occasional dash of humor:

So why did the Met feel the need to put its helicopters on Twitter? Part of its public outreach. The Met wanted Londoners to know that the helicopter overhead was a police helicopter, and why it’s there. Most tweets don’t have photos but are simple and fact-based like this one:

Assisting @MPSWandsworth with several mopeds failing to stop. Other aircraft in the area are not ours.

But it’s also to get people to stop complaining about the racket overhead. As a result of the Twitter account, noise complaints due to the helicopters are down 90%, a Met spokesman, Alex Fedorcio, told Quartz. The account has been more successful than the department expected. Still, going viral is not something the Met tried to do, Fedorcio said. It’s just a happy bonus.
